PVC roofing tiles are primarily made of PVC resin, contain no formaldehyde or benzene compounds, and comply with environmental standards such as GB/T 28907 and GB 18582. They have strict limits on VOC emissions, and actual test results show a high compliance rate. However, be wary of unbranded products that use recycled materials, which may result in excessive heavy metal levels. When purchasing, be sure to request a test report for the specific batch; verbal assurances are not valid.
PVC-coated steel roofing tiles are made primarily from high-density polyethylene and contain no harmful substances such as asbestos or lead. The production process requires low energy consumption, generates minimal carbon emissions, and does not release harmful gases, making them safe for indoor environments and compliant with environmental standards. With a service life of over 20 years, they reduce resource waste, further demonstrating their environmental benefits.
